Prevalence of Extended-spectrum Beta-lactamases (ESBL) Types blaTEM and blaSHV in Klebsiella pneumoniae Strains Isolated from Clinical Samples by PCR in Miandoab, West Azerbaijan
Background and Objective: Beta-lactamases are the most important factors in the resistance to beta-lactam antibiotics among gram-negative bacteria, especially Klebsiella pneumoniae. Nowadays, the prevalence of infections caused by extended-spectrum β-lactamases (ESBLs)-producing K. pneumoniae is increasing, as one of the emerging health problems throughout the world. This study aimed to investi...
متن کاملThe detection of Extended Spectrum Beta-Lactamases (ESBLs) producing Escherichia coli isolated from clinical samples
Urinary tract infections (UTIs) are a stern public health problem and are caused by a wide range of pathogens, but most frequently by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Enterococcus faecalis and Staphylococcus saprophyticus. High frequency rates and increasing antimicrobial resistance among uropathogens threaten to greatly raise the economic load of these infections. Fe...
متن کاملThe prevalence of Escherichia coli strains with extended spectrum beta-lactamases isolated in China
The extended-spectrum-lactamases-producing Escherichia coli has rapidly spread worldwide. Escherichia coli has been becoming much more resistant to β-lactam antibiotics and other commonly available antimicrobials. We investigated the prevalence, resistance, and probable gene type of extended spectrum beta-lactamases (ESBLs) using minimum inhibitory concentrations (MICs) testing and polymerase c...
متن کاملPrevalence of PER-1- type Extended-Spectrum Beta-Lactamaes in Clinical Strains of Pseudomonas aeruginosa Isolated from Tabriz, Iran
Objective(s) The aim of this study was to investigate the presence of PER-1-type ESBLs in drug resistant Pseudomonas aeruginosa isolates. Materials and Methods During one-year period (2008-2009), following isolation and identification of 56 P. aeruginosa, the E-test method was performed for determination of minimal inhibitory concentration of ceftazidim. The isolates that they had MIC≥16 µg/ml ...
متن کاملThe multidrug resistance and production of extended-spectrum beta-lactamases ctx-m, per and ver in Escherichia coli isolates derived from raw dairy samples
The occurrence of extended-spectrum beta-lactamases-producing bacteria is an important public health issue. The aim of this study was to investigate phenotypic and genotypic characteristics regarding the presence of extended spectrum β-lactamase ctx-m, per and ver producing Escherichia coli isolated from raw dairy samples. For this purpose, E. coli were isolated from 247 raw dairy samples (milk...
متن کاملqnr Prevalence in Extended Spectrum Beta-lactamases (ESBLs) and None- ESBLs Producing Escherichia coli Isolated from Urinary Tract Infections in Central of Iran
Objective(s) Extensive use of quinolones has been associated with raising level of resistance. In the current, we focused on assessing the prevalence of Escherichia coli resistance to quinolones and frequency of qnrA, qnrB and qnrS in non ESBLs (extended spectrum beta-lactamases) and ESBLs producing E. coli with blaSHV and blaTEM. Materials and Methods One hundred and fifty E. coli isolates ...
